Trump supporters share more fake news on social media than any other political group, according to a new study from Oxford University. Researchers studied more than 13,000 Twitter users and 47,000 Facebook pages in the days leading up to President Donald Trump's State of the Union Address to determine which social media users spread the most "junk" news. They discovered that Trump supporters on Twitter shared more unreliable news than all other groups combined. On Facebook, extreme conservatives share more junk news than all other audiences put together. The researchers defined "junk news" as "misleading, deceptive or incorrect information purporting to be real news about politics, economics or culture". A team of 12 researchers coded news stories to determine which sites were likely to broadcast this kind of news. The final list included sites like Breitbart News and InfoWars.
